System.TypeException: Invalid integer: 319

Hi,

i am new to Apex coding

 

i want to generate reference like while creating an opportunity based on some cobination of fileds

Opp Number

DE_HP_1

DE_HP_2

DE_HP_3

RD_HP_1

RD_HP_2

RD_HP_3

RD_SR_1

 

 

so to generate ref like above i am writing apex trigger like before insert

 

         String test1 ; 

         String test2 ;  
         String test3 ;  

         Integer test4 ; 


        for(Opportunity ct: Trigger.new)
       {
           test1 = ct.RECORDTYPEID;

           test2 = ct.LEADINGUNIT__C;

           test3 = ct.DIVISION__C;
       }

        AggregateResult[] groupedResults = [select MaxRefNumCount__c) refnum from Opportunity where RefNumCount__c != null 

and RECORDTYPEID = :test1 and LEADINGUNIT__C :test2 and DIVISION__C :test3]; 
        
        for (AggregateResult ar : groupedResults)  
        {
         test4 = Integer.valueOf(ar.get('refnum'));
        }   
       for(Opportunity ct1: Trigger.new)
       { 
         ct1.RefNumCount__c = test4 + 1;   //RefNumCount__c  is Number filed (18,0)
         ct1.OpprefNUm__C= test2 + '_' + test3 + '_'  ct1.RefNumCount__c  ;
       }

 

but while saving opportunity i am getting error like

System.TypeException: Invalid integer: 319: Trigger.OpportunityBeforeInsert 

i am getting error in    test4 = Integer.valueOf(ar.get('refnum'));

 

any body please help me

What's the field type of refnum? 

 

btw-looks like there's a typo in your SOQL:

 

Yours:

[select MaxRefNumCount__c) refnum from

 

My guess: 

[select MaxRefNumCount__c, refnum__c from

HI

i got the solution like below .

RefNumCount__c is a Number datatype .

please check my apex coding style is this ok ? because i am new to Apex

 

           String OppRecordType; 
           String OppLeadingUnit; 
           String OppDivision; 
           Integer refCountValue = 0 ; 
           
           for(Opportunity ct: Trigger.new)
           {
              OppRecordType = ct.RECORDTYPEID;
              OppLeadingUnit = ct.LEADINGCONVERTEAMUNIT__C;
              OppDivision  = ct.DIVISION__C;
           }
          AggregateResult[] groupedResults = [select Max(RefNumCount__c) refnum from Opportunity where  RECORDTYPEID = :OppRecordType and  LEADINGCONVERTEAMUNIT__C = :OppLeadingUnit and DIVISION__C = :OppDivision ]; 
          for (AggregateResult ar : groupedResults)  
        {
            if (String.valueOf(ar.get('refnum')) == null)
            {
                 refCountValue = 0;
            }
            else
            {
                 refCountValue = Integer.valueOf(String.valueOf(ar.get('refnum')));
            }
        }   
        for(Opportunity ct1: Trigger.new)
        {
            ct1.RefNumCount__c = refCountValue + 1;
            ct1.OLDNICENBR__C = OppLeadingUnit + '-' + OppDivision + '-000' + ct1.RefNumCount__c ;
        }

RecordTypeID variable should be of type ID.  Might need to change the type for OppLeadingUnit as well.

 

I haven't used the new aggregation capabilities of SOQL, so I can't speak to that syntax.  Try to compile & test it in a devleoper org if you are worried about messing up production data.

 

 

 

Id OppRecordType; String OppLeadingUnit; //is this just a text value? String OppDivision; Integer refCountValue = 0 ; for(Opportunity ct: Trigger.new) { OppRecordType = ct.RECORDTYPEID; OppLeadingUnit = ct.LEADINGCONVERTEAMUNIT__C; OppDivision = ct.DIVISION__C; } AggregateResult[] groupedResults = [select Max(RefNumCount__c) refnum from Opportunity where RECORDTYPEID = :oppRecordType and LEADINGCONVERTEAMUNIT__C = :oppLeadingUnit and DIVISION__C = :oppDivision ]; for (AggregateResult ar : groupedResults) { if (String.valueOf(ar.get('refnum')) == null) { refCountValue = 0; } else { refCountValue = Integer.valueOf(String.valueOf(ar.get('refnum'))); } } for(Opportunity ct1: Trigger.new) { ct1.RefNumCount__c = refCountValue + 1; ct1.OLDNICENBR__C = OppLeadingUnit + '-' + OppDivision + '-000' + ct1.RefNumCount__c ; }
